INSULATOR.

SPECIFICATION forming part of Letters Patent No. 650,445, dated. May 29,1900. Application filed October 28, 1899. Serial No. 735,082. (Nomodel.)

To (LZZ whom it may concern:

Be it known that I, EMILIO ZERTUCHE, of Puebla, Mexico, have invented anew and Improved Insulator, of which the following is a full, clear, andexact description.

My invention relates to an insulator or support for electric wires, andhas for its object to provide a simple, cheap, strong, and efficientdevice of the above-indicated class.

The invention will be fullydescribed hereinafter and the features ofnovelty pointed out in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a perspective View of my improved insulator. Fig. 2 is asectional plan on line2 2 of Fig. 3, and Fig. 3 is a sectional elevationon line 3 3 of Fig. 2 and showing the insulator attached to a support.

The insulator consists of any suitable ma terial, such as glass orporcelain, and is made substantially in the shape of a rectangular prismthe side edges of which have been rounded off.

In two of its side surfaces, about half-way between the top and thebottom, the insulator is provided with horizontal grooves A, startingfrom opposite ends, and these grooves communicate with a vertical slotA, extending diagonally, as shown best in Fig. 2, and reaching from thetop surface to the level of the bottom of the grooves A. The insulatorat the meeting-points of the slot A with the grooves A is formed withoverhanging projections A and the corners below these projections in theplanes of the grooves A are rounded, as shown at A In a plane at a rightangle to that formed by the Z-shaped passage A A A the other two sidesof the insulator are provided with curved grooves A, which also extendpartly over the top and bottom surfaces of the insulator. These groovesare adapted to receive a wire E, which is Wound around the insulator andaround a supporting-arm D to secure the insulator thereon, as shown inFig. 3.

To strengthen the insulator, an S-shaped piece of metal B maybe embeddedin its bottom surface.

The line-wire C enters through one of the grooves A, passes under the.corresponding tongue A then diagonally across the slot A to anengagement with the round edge A under 5 5 break,that the stretching ofthe wire maybe ef- 6o fected after the wire has been placed in theinsulator, and that the stretching may readily be performed in a veryeflicient manner.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. An insulatorconsisting of a body having a Z-shaped passage the end members of whichextend in opposite side surfaces of the insulator while the central ordiagonal memher extends through to one of the end sur faces of theinsulator.

2. An insulator consisting of a body hav ing substantially-parallelgrooves in opposite side surfaces, and a diagonal slot connectingopposite ends of said grooves and extending through to one end surfaceof the insulator.

3. An insulator consisting of a body having a Z-shaped passage the endmembers of which extend in opposite side surfaces of the insulator whilethe central or diagonal mem ber extends through to one of the endsurfaces of the insulator, the insulator being provided with overhangingtongues at the junction of the diagonal member with the end member ofthe passage.

4. An insulator consisting of a body having a Z-shaped passage the endmembers of which extend in opposite side surfaces of the insulator whilethe central or diagonal memher extends through to one of the endsurfaces of the'insulator, the insulator being provided with overhangingtongues at the junction of the diagonal member with the end member ofthe passage, and with rounded 5 edges below said tongues.
